Can I use a key without a transponder?

A non-transponder key may help a ne'er-do-well get into your car – however, other than that, there isn't much else they'll be able to do! In the vast majority of cases, transponders are linked to an immobiliser system and set up so that if the codes don't match, your engine won't start.

Make no mistake, car security is still as important as ever!

So, how do you avoid car thefts?

There are many things car owners can do:

Parking their car in the garage

Securing it with CCTV

Keeping your car keys out of sight in your home

Speaking of keys however, it’s worth asking whether or not your car’s keys, locks and ignition are up-to-date and using the latest measures to prevent

unauthorised entry!

Transponder vs non-transponder car keys

What is a transponder chip?

Thanks to technology, securing your vehicle has never been more effective, and it’s all thanks to car key transponders. Invented in 1985, transponder keys have become standard in virtually all cars made since 2000. Essentially, a transponder is a tiny chip located in your car keys, usually inside the head of the key. This chip communicates with your car’s on-board computer using RFID (Radio Frequency Identification) technology – the same tech that powers paywave or

Myki.

This chip emits a unique signal. If it doesn’t match the signal coded into your car’s on-board computer, your car won’t start, providing you with an extra

layer of security – something that old car keys can’t offer.

What is a non-transponder car key?

Essentially, any car key that doesn’t have a transponder – that’s to say, the vast majority of car keys from models before the turn of the millennium. Before the mid-90s and early 2000’s, transponders would only be found on luxury, high-end vehicles, leaving most other cars with only minimal physical

security.

Thankfully, since then these features have become standard.

If you’re still driving a car from before this however, you face a higher risk of car theft, as hotwiring techniques and fake keys may still be effective

without the added protection of a transponder.

How do transponder keys work?

As we mentioned before, transponder keys emit a wireless signal that’s synced with your car’s on-board computer. Whenever you approach your car, your transponder and car automatically communicate, going through the following process… Step #1: Your transponder car key sends out a unique radio frequency signal (the transponder code) to the antenna ring of your car’s immobiliser system Step #2: Your immobiliser system then sends a unique code to your car’s computer system Step #3: Once your car receives the computer-generated code, it disables the system and allows your car to start Should any of these steps fail, your car will not disable your immobiliser, resulting in you (or more realistically, someone who’s trying to get away with

your car) getting stranded.

Will a non-transponder key start my car?

A non-transponder key may help a ne’er-do-well get into your car – however, other than that, there isn’t much else they’ll be able to do! In the vast majority of cases, transponders are linked to an immobiliser system and set up so that if the codes don’t match, your engine won’t start.

Car thieves can easily use car picking tools that can make them start and turn your car ignition. Non-transponder car keys are usually used in old car

models that don’t have an immobiliser system.

How do I know if my car key has a transponder?

If you’re unsure whether your car is using a transponder or non-transponder car key, you can always check your car key’s plastic cap to see if it has a

transponder chip.

The plastic cap usually has a small microchip that usually receives the radio frequency signal that sends back to your car computer system.

How do I know if my transponder key is bad?

Transponder keys can protect your car from theft – however, they can also introduce other problems if they fail. Whether it’s because your transponder and your immobiliser are no longer in sync or because of physical damage to the transponder itself, transponder issues

can result in a number of different issues.

Encountering one of these issues? If so, odds are that you’ve got an issue with your transponder keys.

Sign #1: You can’t start your car

The key itself fits. There’s nothing wrong with the engine. But for some reason, your car isn’t responding. If that’s the case, it’s probable that the issue is with your transponder key! Chances are that the ignition aerial inside your car doesn’t recognise your car key. This is rare, but it can happen periodically, resulting in your transponder and car no longer being in sync and using the same transponder code.

The result? Your immobiliser won’t disengage, leaving you stranded.

Sign #2: Lock problems

In some cars, the transponder isn’t just linked to the immobiliser in the engine – in some, it’s also synced to your locks themselves. As such, if your key suddenly stops working (and you’re confident it isn’t an issue with the physical key itself), you may have encountered a transponder

issue.

Sign #3: On and off of emergency signal

When your car’s emergency signal suddenly goes off without you doing anything, or if the alarm activates out of the blue, this can be a sign that your

transponder car keys are not working as they should.

While it isn’t all cars, in many, using a non-transponder key can activate your car’s alarm. This is an extra security measure designed to alert you when somebody is trying to gain unauthorised access to your vehicle. If you notice that your alarm is going off shortly after you insert your keys into the lock or ignition, it may be worth considering whether or not your

transponder is causing the issue.
